The hypothesis of Lee (1976)--that approach and deceleration toward a surface can be controlled through the rate of change of the optic variable tau--was examined for natural human locomotion. In Experiment 1, 12 adults were asked to perform locomotor tasks that required running at speed and then decelerating so that either the hand or head made a controlled contact with a door. In Experiment 2, 12 preschool children performed a relay-running task that required similar control. In Experiment 3… CONTINUE READING
